- 11. The device as claimed in claim 10, wherein the infrared linear sensor is arranged upstream of the edger.
- 12. The device as claimed in claim 10, wherein the infrared linear sensor is arranged downstream of the edger.
- 13. The device as claimed in claim 10, further comprising another infrared linear sensor.
- 14. The device as claimed in claim 13, wherein an infrared linear sensor is arranged upstream and an infrared linear sensor is arranged downstream of the edger.
- 15. An improved method for operating a hot rolling train, said improvement comprising:optimizing a strip width distribution by means of a calculating system, said system determining the position of the ends of the strip by recordation of the radiation from the strip, whereby, depending on the determination of the position of the ends of the strip. activating adjustment corrections to an edger.
- 16. The method as claimed in claim 15, wherein the system comprises an infrared linear sensor having measuring area running transversely in relation to the running direction of the strip.
- 17. The method as claimed in claim 15, wherein the system comprises an infrared linear sensor having measuring area running longitudinally in relation to the running direction of the strip.
- 18. The method as claimed in claim 16, wherein the position of the ends of the strip is recorded upstream of the edger.
- 19. The method as claimed in claim 17, wherein the position of the ends of the strip is recorded upstream of the edger.
- 20. The method as claimed in claim 16 wherein the position of the ends of the strip is recorded downstream of the edger.
- 21. The method as claimed in claim 17 wherein the position of the ends of the strip is recorded downstream of the edger.
- 22. The method as claimed in claim 16 wherein the position of the ends of the strip is recorded both upstream and downstream of the edger.
- 23. The method as claimed in claim 17 wherein the position of the ends of the strip is recorded both upstream and downstream of the edger.
- 24. A system for operating a hot rolling train comprising:at least one edger; at least one linear sensor or determining the position of the ends of a strip; and a means for optimizing a strip width distribution of at least one end of a strip, wherein adjustment corrections to the at least one edger are activated depending on the determination of the position of the ends of a strip.
- 25. The system as claimed in claim 24, wherein the linear sensor is arranged upstream of the edger.
- 26. The system as claimed in claim 24, wherein the linear sensor is arranged downstream of the edger.
- 27. The system as claimed in claim 24, further comprising another linear sensor.
- 28. The system as claimed in claim 27, wherein a linear sensor is arranged upstream and a linear sensor is arranged downstream of the edger.
- 29. The system as claimed in claim 24 wherein the linear sensor is an infrared sensor.
- 30. The system as claimed in claim 27 wherein the sensors are infrared sensors.
- 31. The system as claimed in claim 24, wherein the sensor is an infrared linear sensor having a measuring area running transversely in relation to the running direction of the strip.
- 32. The system as claimed in claim 24, wherein the sensor is an infrared linear sensor having a measuring area running longitudinally in relation to the running direction of the strip.
